Chapter 3 Adjustment Procedures 29

3. Set the synthesizer to deliver a 3V rms sinewave at a frequency of

100 kHz. Connect the synthesizer, the 3V thermal converter, and the

multimeter as shown in Figure 4. Record the exact DC voltage

measured by the multimeter on Line A of the Adjustment Record.

Figure 4. Characterizing the Adjustment Setup

4. Set the synthesizer to deliver a 3V rms sinewave at a frequency of

2 MHz. Adjust the synthesizer's output voltage until the voltage

displayed on the multimeter is within 0.2% of the voltage recorded on

Line A. Record the synthesizer's voltage setting on Line C of the

Adjustment Record.

5. Set the synthesizer to deliver a 3V rms sinewave at a frequency of

8 MHz. Adjust the synthesizer until the voltage displayed on the

multimeter is within 0.2% of the voltage recorded on Line A. Record

the synthesizer's voltage setting on Line D of the Adjustment Record.

6. Set the synthesizer to deliver a 1V rms sinewave at a frequency of

100 kHz. Replace the 3V thermal converter with the 1V thermal

converter. Record the exact DC voltage measured by the multimeter

on Line E of the Adjustment Record.

7. Set the synthesizer to deliver a 1V rms sinewave at a frequency of

8 MHz. Adjust the synthesizer until the voltage displayed on the

multimeter is within 0.2% of the voltage recorded on Line E. Record

the synthesizer's voltage setting on Line F of the Adjustment Record.
